What is a drill and how to handle it?
To date, drills are made of high-speed, alloyed or carbon steels. For work on durable materials they are equipped with heavy-duty, hard-wearing tapes. According to the design features, they are divided into feather, centering, with straight grooves and spiral( for deep penetration).
On processed material they are distinguished as follows: wood, metal, stone and concrete, glass and ceramics, diamond and universal. Each of them is suitable for a certain type of work, it should be considered before inserting a drill into a drill.
With prolonged operation, situations arise when the drill is stuck in the drill, the chuck is broken, dulled or jammed. In such cases, it needs to be extracted, which is sometimes not so simple. We will try to carry out the operation with the least losses.
How do I get a drill from a drill chuck?
Before removing the drill from the drill, pay attention to the design of its cartridge. There are two types of cartridges: key and quick-clamping. The key cartridge is more reliable, especially if you are working in a strike mode. This cartridge is made of metal, therefore, less susceptible to mechanical damage.
Its disadvantage is that before removing the drill from the drill, it is required to open the clamping jaws of the cartridge with a special key.
Plastic quick-action chucks are usually equipped with small drills. Replacement is done by hand. Quick-clamping options are one-way and two-clutch versions. The replacement, of course, is different, but not fundamentally. Before changing the drill in a drill with a double-clutch quick-action chuck, it is necessary to switch your tool to reverse mode, fix the lower clutch with one hand, and unscrew the upper one with one hand.
Replacing the nozzle in a single-arm cartridge is done with one hand, because it is placed only on a drill with an auto-locking shaft.
Critical situation - drill bit stuck
It happens that the working tool is clinching in the cartridge, and he does not want to be taken out. The question arises: how to remove a drill from a drill? To pull it out, it is necessary to clamp the free part of it in a vice. Next, you need to tap the hammer with a hammer on the wooden head over the cams of the cartridge, until the drill bit is out of the quick-action chuck.
If this does not work, remove the cartridge from the drill and soak it in gasoline, or spray it with WD-40 fluid or a foam cleaner. In the key cartridge, you just need to drop a little engine oil.
Sometimes during work, for example, with a reinforced concrete wall with a drill, the drill gets stuck. When the trigger is pressed, the drill buzzes, but nothing happens. It happens when the drill goes deep into the wall and is clamped between the reinforcement and concrete. In such cases, it is necessary to stop pressing the trigger or loosen the drill with the drill.
This will not only lead to breakage of the drill, part of which remains in the wall, but also to the failure of the entire tool. The first thing you need to get him out of the cartridge. After this, another drill is inserted into the drill and a careful knocking out of the concrete around the jammed element begins. At the same time, you should avoid getting hit by a person who is stuck in the wall. Having beaten pieces of concrete around, you can easily extract it with your hands.
